Welcome to the Q&A Forum

Hi David, First, my preference would always be to use 301 redirect to send pages that no longer exist to a new URL. Using a 301 passes link juice and signals search engines that the old page should be de-indexed and the new page indexed in its place. Barring some issue with your rel=canonical tags, which would be the first place to look, I would check other things that can send signals to the search engines about freshness: meta refresh tags update frequency reported in your sitemap custom crawl rate setting in Webmaster Tools Then of course, there is an analysis of the differences between your old design and the new...have you made a significant change to your menu(s) and/or internal linking structure which has made it harder for crawlers to follow links to all pages in your site? Hope that helps, Sha

Hi David, Apologies, in my haste I didnt take in it was the engine page. I hole heartedly agree with the other comments made here. I would also add that, although not the be all and end all, you may find that linking out to to other sites may help the page get indexed as well. If there are any additional, authoritative resources (that are not competition) it may be worth linking to a few of these. Adds value to the user as well.
